FORMULA

This sequence k(m) is associated with the array T(3,2,0) at A125152 as follows: row m consists of numbers of the form Floor[(3^p)/(2^k)] for k=k(m).

EXAMPLE

The pairs (j,k) for the first six rows are

(0,0), (2,2), (2,1), (4,4), (5,5), (7,8).

First term in row m is Floor[(3^j(m))/(2^k(m))],

so for m=1,2,3, the first terms are

1=[(3^0)/(2^0)], 2=[(3^2)/(2^2)], 4=[(3^2)/(2^1)].
